What is a plate boundary?

Back

A plate boundary is the edge where two tectonic plates meet, leading to various geological activities such as earthquakes and volcanic eruptions.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are divergent boundaries, convergent boundaries, and transform boundaries.

Front

What occurs at a divergent boundary?

Back

At a divergent boundary, tectonic plates move away from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, which can result in one plate being forced under another, leading to subduction.

Front

What happens at a transform boundary?

Back

At a transform boundary, tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle.

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountain ranges are commonly formed at convergent boundaries due to the collision of tectonic plates.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by the upwelling of magma at divergent boundaries.

Front

What is a hot spot volcano?

Back

A hot spot volcano is a volcano that forms in the middle of a tectonic plate, away from plate boundaries, due to a plume of hot material rising from the mantle.

Front

What is the San Andreas Fault?

Back

The San Andreas Fault is a transform boundary located in California, known for its significant earthquake activity.
